Abstract

Today, XML is the format of choice to implement interoperability between systems. This paper addresses the XML-based query processing for heterogeneous OLAP data warehouses in a federated architecture. In our approach, XML, as an intermediary representation, can be used as a basis for federated queries and queries for local OLAP data warehouses, whereas XML DTD can be used for query language definition and validation of a XML federated query.
